40 curled, the ca1n`27 has'moved yone revolution .and consequently 'thelifting plate 30 the lifting plate 30. A resilient buffer 31 issupported by the stationary plate 7 so as to absorb the shocks to thelifting plate when the plu'n'gei` 29 drops-to the cut -away portion ofthe v lifting cam as shown. by

ring 36 between vwhich the .petals of the stampedout layers ofwork?are'po'sitioned preliminary7 to the curlingfand rolling operation,subsequently to 'be described. The receiver 33 is preferably formedwith side arms orextensions y38 which slide inthe guides 32.. when thereceiver mechanism isl tripped and is` moved from its centeredpositionas shown by Figure l1 tothe position shown by` Figure l2 sothatl the stamped workvmay be placed within said receiver preliminary tothe curling operation. Connected to the wall of the receiver 33, is alink 38a and an arm 39y pivotally Vconnected las at'y 40 and held undertension by ajspring 4l'con'nected to a'bracket 42a, attached to thestationary plate 7. A catch Ao'rflock 42 is ApivotedasV at- 43 to ftheadjusting block 65 and'adapted to engage the edge of the ,wo'rkreceiverl 33 when the latter is centered, said locking devicebeing`,released when the lifting Yplate 30`drops,

which operation isv effected after the curling or rolling operation iscompleted. In other words, the operationcf they lifting plunger 29, and,the lifting plate 30'wh`ich` vcarries the receiver 33 is timed withthecurling mechanismfso that. when the petals are n is dropped and thereceiver 38 is automatin. cally released or moved from the position asshownby Figurek 11 to the position shown I by Figure 12 whereby theworkmay be removed?.andv other work inserted in there- Reference beinghaepaaieeiariy te rigures 6 ,to9 inclusive of the drawings, show- Y ving ythe details of the' curling mechanism, it

Ewill be observed that the curlers "are operati VAelfin unison and aretimed `so that thefc'urling operation is effected during onelrevolutienofthe shaft. y The supe'rstructure cf 4frame 8k supports a casting 43 towhich the Vguides l44 are secured."r` Heccentric l45, finounte'd onftheshaft carries aV block y.46, slidfablein the guide; Connected to theblock A46' is'v Ia; vertical shaftv or. rod 47, which carriesaljslottQdf'Ilnular vplate ,485" i The yslotted jwhichfcomprises afpluralityvl of at their lopposite ends'connected to bell crank levers50. Each" bell crank lever is provided with teeth 5l for` operating .therackbars 52,v whichk slide in guide 53,"supported by th'e. frame. Onrthe inner end of each rack bar 52, ther-eis provided-a curved arm 54which carries a curling roller 55.V The curlingrollers and the rack`bars52 are,`aclapted tO voperate outwardlyv or .away from the center v37 ofthe form or blanks to be curled, -it be- 'ingv of courseunderstood'thatthisl operation takes place when. the'plungerj29v andthe` lifting plate has beenmovedupwardly Y and while the block 46 islbeing moved up- -wardly by the action of the "eccentric above referredto.` The superstructure 8 also carvriesa block 56, the blockcarryingathread'-` ed'member 59 at whose lower vend isv held a presserplate 57,' a spring 60 being interposed between the block and thepresser; plate iso" as to bear fflilyonk the central. portionef thework, positioned in the' receiver. `j In order to regulate the extentofthe'movement of the bell cranklevers'V andthe meshing;

rack bars, the said ybellfcrank levers have lattachedthereto a screw-61,'` which extends through theslotted plate 62 and is retained knurlednut 63. 'Under certain circuni stances, it 'may be desired to increaseor decrease the erztenty of the petalcurling 1in a predetermined,adjustedposition bythe 2 operation of they rollers carried 'bythe `rackbars v52 and consequently, an adjustment ymust 'be provided for thethrow of the bell' crank lever.. In Figure wef'hzwealsok shownja meansfor centering'.the-"fwork'receiver 33 which consists of an adJustablestop 65 which maybe moved inwardly; or

outwardly by the threaded screwufVVV` The operation lofl thermachine isunder theY control of the lever "mechanism" which consists of theverticalrod`22 connected to one end of the lever 22, the lowerend of therod `22aubeing pivotally connected as at-23a toV the actuating levei`24a"softhat when' the rod '22a is .movedk upwardly and out ofengagevmentwith the collar 18, the shaft will rotate kvery slowly. e Thee'plunger29 will then move upwardly andl the shaft'47 downwardly to. permit the'curlers to engage" the werk. f It vwill be observed that'VK the clutchshifting lever 22 is provided with a knife edge 22b "which `is adaptedk'to ride "between/"the bevelled edge2l of the pin and the collar 18thusv releasing Q the' clutch', 1 after i the shaft'l'()v vhas made one'complete revolution. At this point,

itwill be Lrecognized"that the curling opera ltionl hasbeen effected'and that the plunger Y`29 has dropped, the shaft 47fraised'aiid'the workreceiver hasbeen inoved'tofth'eposition shown byuFigure l2 yfrom whichvthe work may be removed and new work inserted. i

. Any number *ofthe leversgrack bars? an'd connecting"elements may-bediseen'neeted or c c rendered inoperative when diiferentftypefor styleof forms are to b-e used, which require curling. In actual practice, thematerial of the blank is of tissue paper or thin fabric, thus permittinga numberto be curled or rolled in one operation. The work is re movedfrom the receiver 33, the curled work is then separated and made intoiowersor" other designs.
